交互分析模型在协作虚拟环境中实现动态兴趣管理

目前，许多传统的协作式虚拟环境应用主要采用Grid和Locale概念来实现虚拟环境中用户的兴趣管理．但是，当其应用在基于虚拟人的社交性协作仿真时，这些基于位置的兴趣管理方法具有一定的局限性．针对社交性协作仿真这一类虚拟环境应用，提出一种新的在协作虚拟环境中采用动态交互分析的兴趣管理模型．首先定义了兴趣网络和兴趣矩阵的概念；然后描述了交互分析方法，通过该方法来实时分析虚拟人的兴趣焦点；最后在该模型的基础上实现了一个原型虚拟环境系统，并演示了该模型在优化场景绘制和协同感知上的作用．

Correlation Analysis Model for Dynamic Interests Management in Collaborative Virtual Environment

Currently many traditional collaborative virtual environment(CVE) applications mainly used Grid and Locale to implement interests management. But these approaches had limitations in virtual human based social environment simulation. Aiming at such kind of applications, we proposed a new interests management model with dynamic correlation analysis in CVE. The concepts of Correlation Network and Interest Matrix were defined and a correlation analysis approach to find out the interest focus of virtual humans was presented. A prototype virtual environment system was implemented to demonstrate the effects of our approach in optimizing the visual rendering process and highlighting the collaborative perception.
